iTi Performance Motorsports has developed this new race bred Exhaust System for the Polaris RZR & RZR-S. This exhaust is made from Stainless Steel and utilizes a 1/4 inch thick header flange for durability. The 1 1/2 diameter OD 1 3/8 diameter ID equal length tubing is then bent to meet with an X Pipe. Exhaust travels out of the X pipe to a Y Merge Collector. This pipe dramatically increases the bottom end torque of the RZR. The X Pipe design helps equalize the exhaust pulse thus producing more bottom end power. The exhaust enters the muffler with a 1 3/4 inch diameter pipe and exits the muffler through a 2 inch diameter opening. This muffler is equipped with a approved spark arrestor.This new product from iTi Performance Motorsports is a must for your RZR or RZR-S
